Method for determining black carbon in residues of vegetation fires
Article Abstract:
A method for determining black carbon (BC) in residues of forest fires was developed based on solubility, vapor pressure and oxidative stability and compared to two thermal methods quantifying BC in aerosols. Treatment and extraction methods showed that BC occupies a larger fraction of the total carbon in ash residues than in ash. Solvent extraction showed similar results, suggesting that the method is an effective approach for measuring BC content in ash residues from vegetation fires.

Chloride interference in the analysis of dissolved organic carbon by the wet oxidation method
Article Abstract:
The effects of chloride interference on the analysis of the aqueous dissolved organic carbon by high-temperature, persulfate oxidation method with short reaction times are discussed. Aquatic fulvic acid samples were analyzed for total organic halogen absorptions and volatile organic compounds. Employment of short reaction time caused the presence of chloride in concentrations greater than 0.02 to interfere with the analysis of aqueous DOC concentrations by the wet oxidation method.

Complete heavy metal removal from fly ash by heat treatment: influence of chlorides on evaporation rates
Article Abstract:
The evaporation of heavy metals during heat treatment of fly ash follows a first-order rate law. This was gleaned from a simulation using fly ash from a municipal solid waste incineration plant and synthetic powder mixtures ranging in temperature between 670-1000 degrees C. Chlorides present in the fly ash, largely as NaCl, were found to heavily influence the degrees as well as the rates of evaporation of the heavy metals.
